Question
Which of the following approaches is an effective way of protecting yourself against SQL injection?
Solution
-
Use Prepared Statements (Parameterized Queries): The use of prepared statements ensures that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker.
-
Use Stored Procedures: Stored procedures can provide the same level of protection as parameterized queries. The use of stored procedures can help reduce the occurrence of SQL Injection attacks.
-
Escaping All User Supplied Input: This technique should only be used as a last resort, when neither of the above are feasible. Escaping user input involves manipulating the data the user supplies to ensure that it does not interfere with query structure.
-
Least Privilege: Do not assign DBA or admin type access rights to your application accounts. An attacker can do far less damage
